[0002] In the prior art, a 90-degree connector (or right-angle connector) for high voltage generally includes a conductive housing, an insulating inner housing, a cable assembly, a bus bar, and a connection assembly. An mating port for mating with an mounting hole on an mounting panel is formed at the bottom of the front end of the conductive housing, an mounting port for mounting the connection assembly is formed at the top of the front end of the conductive housing, and a rear port for inserting the cable assembly and the insulating inner housing is formed at the rear end of the conductive housing. One end of the cable assembly is inserted into the insulating inner housing. One end of the bus bar extends into the insulating inner housing through the mating port on the conductive housing, and the connection assembly enters the insulating inner housing through the mounting port on the conductive housing and fastens one end of the bus bar to the connection terminal of the cable assembly, so that the bus bar is electrically connected to the cable of the cable assembly.

[0003] In the prior art, to prevent dust from entering through the mounting port of the conductive housing and prevent electromagnetic leakage, a sealing ring and a shielding cap need to be installed on the mounting port of the conductive housing. This results in a complex structure and increased cost of the connector. In addition, the distance between the shielding cap and the connection assembly is relatively close, and it is easily broken down, reducing the use safety of the connector. Summary of the Invention

[0004] The object of the present invention aims to solve at least one of the above problems and defects existing in the prior art.

[0015] According to another exemplary embodiment of the present invention, an insulating layer is wrapped on the head of the connecting member, so that the head of the connecting member is electrically isolated from the conductive outer shell and the operating tool for operating the connecting member.

[0016] According to another exemplary embodiment of the present invention, the cable assembly further includes a shielding connecting member, one end of the shielding connecting member is sleeved and crimped to the shielding layer of the cable, and the other end of the shielding connecting member is sleeved on the rear end of the insulating inner shell and is in electrical contact with the inner wall surface of the conductive outer shell to electrically connect the shielding layer of the cable to the conductive outer shell.

[0017] According to another exemplary embodiment of the present invention, the conductor end of the cable and the connecting terminal are flat, and one end of the connecting terminal is stacked and welded to the conductor end of the cable.

[0018] According to another exemplary embodiment of the present invention, the cable assembly further includes a seal, a through hole allowing the cable to pass through is formed in the seal, the seal is sleeved on the cable and is installed in the rear port of the conductive outer shell, and the seal is squeezed between the inner peripheral surface of the rear port of the conductive outer shell and the outer peripheral surface of the cable to seal the rear port.

[0019] According to another exemplary embodiment of the present invention, the cable assembly further includes: a rear end cap, sleeved on the cable and adapted to be latched to the rear end of the conductive housing; and a cable clip, sleeved on the cable and disposed between the rear end cap and the seal. When the rear end cap is latched to the rear end of the conductive housing, the cable clip clamps the cable under the extrusion of the rear end cap to fix the cable.

[0020] According to another exemplary embodiment of the present invention, the rear end cap includes: a cover plate portion; a latching portion that latches to the rear end of the conductive housing; and a tapered portion connected to the cover plate portion and formed with a through hole allowing the cable to pass through. The cable clip includes: a substrate portion, clamped between the seal and the cover plate portion of the rear end cap and formed with a through hole allowing the cable to pass through; and a plurality of elastic claws, connected to the substrate portion and distributed at intervals around the through hole on the substrate portion. The plurality of elastic claws extend into the through hole of the tapered portion and clamp the cable under the extrusion of the tapered portion.

[0021] According to another exemplary embodiment of the present invention, a flange portion for mounting to the mounting panel is formed on the conductive housing, and a through hole allowing a threaded connector to pass through is formed on the flange portion, so that the conductive housing can be mounted and fixed to the mounting panel through the threaded connector passing through the through hole.
